SPECIFICATION forming part of Letters Patent No. 521,492, dated June 19,1894. Application filed February 23, 1894i $erial No- (Nb model) To aZZwhom it mag concern:

Be it known that we, GEORGE W. AULMANN and WILLIAM R. HARRIS, citizensof the United States of America, residing at Des Moines, in the countyof Polk and State of Iowa, haveinvented a Steam and Water Separator andThrottle-Valve Combined, of which the following isa specification.

Heretofore the straight end of a steam supply pipe has been extendedinto the top of a separator chamber and in concentric position with thechamber in such a manner as to produce an annular space of uniform widtharound that portion of the supply pipe inside of the chamber so that thesteam discharged downward into the chamber would rise and escape throughan eduction tube at the top of the chamber and drops of water dischargedfrom the supply pipe descend into the bottom of the chamber. But suchdevice does not separate all the water from steam as required to allowonly dry steam to escape from the top portion of the chamber ascontemplated by the invention hereinafter set forth,pointed out in ourclaims, and illustrated in the accompanying drawings, in which-- Figure1 is a side view (partly in section) of our complete device. Fig. 2 is aside view taken at right angles relative to Fig. 1, showing the valveoperating mechanism. Fig. 3 is a horizontal sectional view through theline m m of Fig. 2.

A represents a valve chamber adapted to be fixed on top of the steamchest A of an engine.

B is the steam separator formed integral with the valve chamber A, ordetachably connected therewith as indicated by dotted lines in Fig. 1.The top end of the separator chamber is contracted and adapted to befixed to a steam supply pipe B An orifice in the concavo convex bottomof the separator chamber is adapted to be connected to a steam loop ortrap to return the water of condensation to the boiler.

C is an open-ended steam conductor on the gral part of the separatorchamber B. Its upper end is connected with the valve chamber A and itslower end is bell-shaped and in concentric position with the wall of thechamber A and close to the wall so that there will be a narrow annularpassage for the steam that descends from the supply pipe into theseparator chamber and then passes upward through the tube 0 and throughthe valve chamber to the steam chest A D is the valve, D the valve stemand D a hand wheel on the end of the valve stem. In the practicaloperation of our invention whenever steam and water descend from thesupply pipe into the separator the steam will be accelerated in speed,as it passes through the narrow annular passagebetween the wall of thechamber B and the bottom edge of the bell-shaped mouth of the separatortube 0, and then upward through the tube and the valve chamber to theplace where it is to be utilized for operating machinery.v The reversedirection of the steam thus caused within the separator chamber and theincrease of speed in its passage resulting from the contracted annularpassage way between the wide mouth of the'separatortube O and theconcentric wall, of the chamber B, as it is reversed, cause the water inthe steam to be separated from the steam by the centrifugal forceresulting from the reverse motion of the steam as the steam passesaround the lower edge of the wide mouth of the separator tube 0. It isobvious that a complete separation of water from steam is thusautomatically effected and that dry steam only will pass from theseparator chamber into the engine, pump or system of piping as the casemay be.

We claim as our invention 1'. A steam and water separator and throttlevalvecombined, consisting of a valve chamher and valve and valveoperating mechanism, and a separator chamber connected with the valvechamber and also adapted to be connected with a steam supply pipe at itstop end and provided with an openingat its bottom, and a concentricopen-ended tube that extends downward from the valve chamber andterminates in a bell-shaped mouth in the central portion of theseparator chamber, to produce a contracted annular steam passage way atthe lower end of the separator tube to operate in the manner set forth.

2. In a steam and water separator, an openended separator tube, having aflaring or enlarged bell-shaped mouth at its lower end, in combinationwith a separator chamber adapted to be connected with a steam supplypipe at its top end tonproduce a contracted annu-tv lar steam passageway at the bottom of the separator tube and a throttle valve at theupper end of the tube, and provided with an orifice at its lower end forconducting water from the separator chambelgto operatein the manner setforth for the purpose of producing dry steam. a

3. In a steam separator, a separator chamber having an open top adaptedto be connected with a steam supply pipe and an open-
